CHAIN.

SPECIFICATION forming part of Letters Patent No; 518,484, dated April 1'7, 1894.

Application filed June 23, 1893- To all whom it may concern.-

Be it known that I, RICHARD A. BREUL, a citizen of the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Chains; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,which form a part of this specification, and in which Figure l is a perspective view of a piece of my improved chain. Fig. 2 is an enlarged perspective view'of one of the links of said chain. Fig. 3 is a front, and Fig.4 is a side view of the same link. Fig. 5 is a detail view, illustrating the manner of bending and interlocking the ends of the wire to form the link.

Like letters of reference designate corresponding parts in all the figures.

My invention relates to chains composed of links made of wire and adapted for general purposes where a light, yet strong and durable chain is required; and it consists in the novel and peculiar construction of the individual wire links as will be hereinafter more fully described and particularly pointed out in the claim.

On the accompanying drawings, the reference letter A denotes a piece of any suitable wire, which is bent, by suitable machinery designed for the purpose, so as to form two loops, B and C, in alignment with each other and in the same plane. In forming these loops, starting from that end of the piece of wire which is marked by the letter ct, on Fig. 5 an offset b is first formed, and the wire is then bent or doubled upon itself to form the upper loop B, until a point, is reached, opposite to the oifset Z). At this point the wire is bent inwardly, so as to form an offset 0. Below this offset the wire is again bent outwardly, and then in a downward direction, doubled upon itself, to form the lower loop C. The left limb C, of this loop passes behind or back of, the ofiset 6, being bent inwardly, just opposite to the offset a on the other side of the link, thus forming an offset Serial No. 478.600. (No model.)

0, and a narrow part or neck D; and from this point the wire is continued upwardly, back of and adjacent to the first loop B, so as to form a second loop B until the contracted middle part D is again reached. At this point the said limb is bentoutwardly forming an offset 19 and the link is completed or closed by forming eyes at and c, on the projecting terminals of the wire, which inclose the oifsets or shoulders I) and con opposite sides of the neck D. In this manner I form a double looped link, one of the loops (B B) of which comprisesa double thickness of wire. The chain is built up by connecting, during the process of their construction, a suitable number of these links to form a chain of any required length. It will thus I be seen that a butt joint is formed between the ends at and e, and the contiguous surfaces of the wires B and B. This forms a very strong, light, and durable chain, which can be manufactured at small expense by the use of special machinery constructed for the purpose.

No amount of strain or tension can sever the chain by unhooking or untwisting the ends of the Wire, and the chain can only be broken by rupture of the wire.

Having thus described my invention, I claim, and desire to secure by Letters Patent of the United Statesa As an improved article of manufacture, a chain of wire links, each link comprising a loop B, B, of two contiguous thicknesses of Wire, and a loop C, C, of a single thickness in the same plane; said loops consisting of a single continuous piece of wire bent into olfsets I), 0, Z), and c, with a narrow space or neck D, therebetween; the ends (1 and e of the wire being secured to the offsets cand 0', whereby a buttjoint is formed between said ends and the contiguous surfaces of the wire, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

RICHARD A. BREUL.
